Configuration Requirements - AddSecure IRIS-4 Technical Reference Manual


The terminal should be powered from an EN54-4 compliant power source, such as a model from the
Elmdene ST range.

The terminal must be mounted in an Access Level 3 protected enclosure compliant with the requirements
of either EN54-2 (Fire detection and fire alarm systems – CIE) or EN54-4 (Fire detection and fire alarm
systems – Power supplies).
If there is not sufficient space to mount the terminal within the existing CIE or power supply cabinet, an
alternative is to use a separate EN54-4 compliant power supply cabinet. A model from the Elmdene ST
range is recommended.
If the enclosure used is not actually used to house the power source, then the enclosure must be mounted
against the power source enclosure so the power cable between the two cannot be the subject of tamper
or accidental damage.

The interface to the fire control equipment should be via terminal inputs (pins) and relay outputs, as
described below. The terminal's "Dial Capture" interface that emulates a PSTN line should not be used as it
does not provide adequate status signaling back to the control equipment. Serial communication lines can
be used for more information but must not be the primary signaling method.

Configuration requirements

Run through the Installation Wizard, see chapter 5 "Configuring the terminal" in the normal way. Make sure
that for pins 1 and 2, the Pin input alarms are configured for SIA or CID and are enabled. If a separate
enclosure for the fire panel is being used, monitoring for tampers must also be enabled.
If an EXT1/EXT2 Expansion board is installed, you must use pins 9 & 12 for monitoring of the PSU. Confirm
these are ticked in the Installation Wizard, see section 5.6.3 "Pin Alarms".
Other alarm inputs can also be enabled if required from the Settings menu, but do not change the above
settings for inputs 1 or 2 or inputs 9 and 12 (if used).
Note: After the EN54-21 Fire mode is selected, it is essential that no other changes are made to the settings
for Pin 1 or Pin 2 or to the Relay A or B outputs as this may invalidate conformance to EN54-21:2006.
Use the Settings «Extra Features» menu to set the 'EN54-21 Fire' mode.
When this mode selected, input pins allocated for the fire application are as follows:

Input pin 1 – Fire Alarm/Restore – open circuit = alarm
 Input pin 2 – Fire Alarm Fault/Restore – open circuit = fault

Input pin 9 – AC Power Trouble/Restore – open circuit = fault

Input pin 12 – System battery Trouble/Restore – open circuit = fault
Note: For inputs 9 & 12 you will need the expansion board EXT1 (12 pins) or EXT2 (12 pins + PSTN) fitted.
